Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

CRISPR-Cas9 is a gene-editing technology that allows scientists to make precise changes to DNA. CRISPR-Cas9 works by using a guide RNA molecule to direct the Cas9 protein to a specific location in the genome. Once the Cas9 protein is bound to the DNA, it can cut the DNA at that location. This allows scientists to insert, delete, or modify genes.
